21 | # tests for exception-handling support | |
22 | # Written by Satish Pai <pai@apollo.hp.com> 1997-07-23 | |
23 | ||
24 | # This file is part of the gdb testsuite | |
25 | ||
26 | # Note: These tests are geared to the HP aCC compiler, | |
27 | # which has an idiosyncratic way of emitting debug info | |
28 | # for exceptions -- it uses a callback mechanism, which | |
29 | # is different from the way g++ records exception info | |
30 | # for debugging | |
31 | ||
32 | # The tests are in two parts; the first part deals with | |
33 | # statically linked (archive-bound) executables, and the | |
34 | # second part repeats those tests with dynamically linked | |
35 | # (shared bound) executables. (In the latter case we use | |
36 | # a different mechanism to get the address of the notification | |
37 | # hook in the C++ support library.) The tests themselves are | |
38 | # the same in both parts. | |
39 | # | |
40 | # IMPORTANT: | |
41 | # --------- | |
42 | # IF YOU CHANGE A TEST IN ONE PART MAKE SURE YOU CHANGE IT | |
43 | # -------------------------------------------------------- | |
44 | # IN THE OTHER PART TOO! | |
